Power detector resolution: 0.5dB+/-1dB.
Minimum discernible signal: -102dBm@30kHz RBW.
Phase noise of -90dB/Hz at 100kHz offset, -115dB/Hz at 1MHz offset.
No spur dynamic range when using 30kHz resolution bandwidth of 70dB.
Manually selectable resolution filters at 3, 10, 30, 100, 300, 600 kHz. Automatically selects one of 57 resolution filters.
On-screen resolution of 51, 101, 145, or 290 measurement points.
Scanning speed of over 1000 points/sec using the maximum resolution filter.
Automatic optimization of the actual scan points to ensure coverage of the entire scan range, regardless of the resolution bandwidth selected.
Spur rejection option for evaluating whether certain signals are internally generated or actually present in the input signal.
High input mode specifications:
(High input mode is low IF reception achieved using a second receiver, without pre-mirror and spurious filters)
Input frequency range: 240MHz to 960MHz
Input impedance is frequency dependent and deviates from 50 ohms.
Since there is no input band filter, strong input signals outside the 240MHz to 960MHz range cause in-band signal distortion.
Absolute maximum input level of +10dBm without attenuation.
Third-order modulation product (IIP3) with an input cutoff point of -5dBm.
1 dB compression point at -6 dBm with no attenuation.
Power detector resolution of 0.5dB and frequency linearity of +/-1dB.
Absolute power level accuracy of +/- 1dB after power level calibration.
Minimum discernible signal using a resolution bandwidth of 30 kHz - 115 dBm.
Frequency accuracy is equal to the selected resolution bandwidth
No spur dynamic range when using a 30kHz resolution bandwidth of 50dB
Manually selectable resolution filters at 3, 10, 30, 100, 300, 600 kHz Automatic selection of one of 57 resolution filters.
Selectable 25dB to 40dB frequency dependent input attenuator. Activating this attenuator increases the power level error to +/-10dB.
Screen resolutions of 51, 101, 145 or 290 measurement points.
Scanning speed of over 1000 points/sec using the maximum resolution filter.
Automatic optimization of the actual scan points to ensure coverage of the entire scan range, regardless of the selected resolution bandwidth.
Low output mode specifications:
Sine wave output with harmonics below -40dB of the fundamental.

Output level can be between -76dBm and -6dBm in 1dB steps
Selectable AM, narrowband FM and wideband modulation or swept output over a selectable frequency span
(AM modulation function is implemented using a quick change of the front attenuator, FM modulation is implemented using a quick modification of the output frequency, not standard precise modulation, can be used for simple intercom reception tests, but not as a precise reference)
High output mode specification:
Square wave output
Output frequency range from 240MHz to 960MHz (minimum frequency step of 312.5Hz)
Output level can be selected in variable increments between -38dBm and +13dBm (higher attenuation is achieved using RF switch leakage, with higher frequency attenuation becomes larger, there will be a relatively large error)
Selectable narrowband FM and wideband modulation or slow sweep in the selectable frequency range (FM modulation is achieved using rapid modification of the output frequency, not standard precise modulation, can be used for simple intercom reception tests, but not as a precise reference)
Reference signal generator specification (for self-test or to output reference clock for external devices)
Optional square wave output with a basic value of -25dBm, connected to high input/output.
Frequency can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz or 30MHz.
Limitations
Because the tinySA`s internal components were carefully selected to strike a balance between performance and cost, you must be aware that the tinySA has significant limitations compared to professional spectrum analyzers.
The internal phase noise sets a clear lower limit for phase noise measurements.
The minimum resolution bandwidth of 3kHz prevents more detail of the spectrum from being seen.
Very limited mirror rejection for high inputs (240MHz to 960MHz) and only one level of optional built-in attenuator make complex signals difficult to resolve.
The optional input attenuator for the high inputs is frequency dependent and varies between 25dB and 40dB.
At lower resolution bandwidths (below 30kHz), the scan speed can be slow.
Masking and filter performance limitations may cause some mirroring and spurious to be visible. tinySA offers a spurious cancellation menu that can be set for spurious reduction by experienced users, but care needs to be taken with possible uncertainties.
Below 0.1MHz, sensitivity begins to decrease.
Below 1MHz, it is recommended to disable AGC and enable LNA if possible to obtain the best quality of measurement.
When using the provided telescopic antenna or low RBW, attention should be paid to the tinySA MCU interference at 48MHz and its harmonics.
